No way I think it's a Winegrud 4bay ok channel master one of the best ANTENNA manufactures that used a ham Radio guy to design ota box with IT'S ATSC performances
New OLD school technology white space ? Low band vhf BROADCASTING channel's 2-6
Is on the come back fcc dumping a lot of money on equipment for the low band vhf BROADCASTING station and is the new antennas and cooled transmitter 's I think the
Low power vhf stations on the RECEIVE end result will be a strong signals.QSL?

That top antenna would almost certainly be two antenna's
modified into one. I imagine it is NOT very efficient or
effective receiving signals 180 degrees apart. i have come
up with a much better alternative to receive UHF signals
180 degrees apart. It is much more efficient than removing
the reflector.

Hi Joe, I have to agree with you it looks like they cut two RadioShack VU160 antennas in half, joined them and called it an antenna.,Lol!

I'm not sure what they were doing, the construction looks old, it was probably done in the 60s or 70s. I just happened to catch it out of the corner of my eye do to my severe ADD. (Antenna Distraction Disorder)!

I've never seen so many different antennas in my life then in Kenosha which I have dubbed "antenna town". Also, lots of towers.

Okay, I give up what do you do to receive bi-directional without removing reflectors?

It does look like a custom mod.
It looks like it would perform about as well as Bob's present system.

Ouch! Which system? My latest failure is the combining of two C4 Max's. Actually, you're right, I'm still looking for the ultimate solution. To be honest with you though I'm having fun and learning a ton. I'll probably write a thread, "What not to do" ,LOL !

I would like to know also.

I'm pretty good at making friends, I've been in business for almost 30 years but knocking on somebody's door out of the clear blue and asking them about their antenna might shock them. Still, the temptation is there. But I'll bet the guy is probably more than willing to talk about his system, he's probably an enthusiast. Who knows, he might even be on this site!

Now it's my turn to say Oops! I meant no insult, Bob.

What I meant was that having two combo antennas aimed in opposite directions is a lot like having two UHF/VHF pairs aimed in opposite directions (not the C4MAXs). In both cases, you have the same combining problem.

I don't consider your experiments with two C4MAX antennas a failure; you learned a lot from it. I have been following your posts on HDF and have found them interesting (especially the SDR scans), but haven't been able to make any useful suggestions. You already have my thoughts about combining.

Rabbit, hahaha, I'm just messing with you! I know you well enough to know, you're a good man with a good heart, and anyone who put up with my A.D.D. (antenna distraction disorder) and keeps answering questions is a saint in my book!

I do know your thoughts about combining, I'm just trying to get the one input solution figured out. There's been a lot of good help.

But what I'm waiting for is JoeAZ's solution to combining two antennas without taking the reflectors off. Come on JoeAZ let's hear it, stop teasing

Okay Rabbit, have you ever seen two antennas put together like that? I would say by his edition of the 3 eight bay antenna, he probably wasn't happy. One day when I get a chance I might knock on his door!

This antenna IS bi-directional; it has more gain than a bi-directional dipole, but less gain than the Stellar Labs 30-2475. It still has the potential problem of co-channel interference from the two directions.

Yes it does but if you set them up right if you tock too the antenna manufactures and let them know what 2antennas you are looking to use pleas
remember that they are both hi gain ANTENNAs and the space between the two
Is very important if it was 4ft apart and find tune them by using the TV sets
